B) Lysosomes
C) Endoplasmic reticulum
D) Mitochondria
B
Feedback:
Lysosomes are membrane-covered organelles that contain specific digestive enzymes that can break down proteins, nucleic acids, carbohydrates, and lipids. They are responsible for digesting worn or damaged sections of a cell when the membrane ruptures and the cell dies. The Golgi apparatus prepares substances for secretion by processing and packaging them in vehicles to move through the cell membrane. The endoplasmic reticulum provides a large surface for chemical reactions within the cell. Mitochondria are the power plants of the cell.
